I expect the RB's to split out wide quite a bit of the time and be utilized in the tunnel and bubble screen game. During every other passing play we have, if there is a RB in the backfield they will be out in a pattern in the flat, the curl zone or on a wheel route unless they are required to stay in a block. Keeping a back in to block is counterproductive IMO as a back releasing with a pass floated over the incoming rusher puts the defender in a bad spot so I don't expect our backs to have to pass block in a lot of situations.
